Description
Summary:Porous tantalum trabecular metal biomaterial has a similar structure to trabecular bone, and was recently added to titanium dental implants as a surface enhancement. The purpose of this prospective pilot study was to describe 5-year survival results and crestal bone level changes around immediately-provisionalized Trabecular Metal Dental Implants. Eligible patients were adults in need of ≥1 implants in the posterior jaw. A non-occluding single acrylic provisional crown was in place for up to 14 days before final restoration. Clinical evaluations with radiographs were conducted at each follow-up visit (1 month, 3 months, 6 months, and 1 to 5 years). The primary endpoint was implant survival, characterized using the Kaplan-Meier method. The secondary endpoint was changes in crestal bone level, evaluated using a paired t-test to compare mean crestal bone levels between the baseline, 6-month, and annual follow-up values. In total, 30 patients (37 implants) were treated. Mean patient age was 45.5 years, and 63% were female. There was one implant failure; cumulative survival at 5 years was 97.2%. After the initial bone loss of 0.40 mm in the first 6 months, there were no statistically significant changes in crestal bone level over time up to 5 years of follow-up.
